If it's the 2.8 MFi in his pics then it will not have a choke..
TBH... I hate K-Jet. I spent 3 hrs trying to revive my m8's MK2 golf 16V after a 6 month layup!!
Does the 2.8 have the cold start valve, that can be rigged to spray a little fuel in if the main injectors are not firing..
Other than that and lifting the air plate to stimulate fuel preasure I don't remember much about the 2.8 MFi set up.
